Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RNF14FTD232R is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 232 Ohms
• Tolerance: ±1%
• Composition: Metal Film
• Package type: Axial through-hole
• Compliance: ROHS3 Compliant

Allowable Variations:

• Power rating: Equal or greater than 0.25W
• Temperature coefficient: Equal or lower absolute value
• Operating temperature range: Equal or greater upper limit
• Physical dimensions: Minor variations acceptable within axial package constraints

The CMF55232R00FHEB qualifies as a substitute because it maintains identical resistance, tolerance, and composition while offering enhanced specifications in power rating (0.5W vs 0.25W), temperature coefficient (±50ppm/°C vs ±100ppm/°C), and maximum operating temperature (175°C vs 155°C).

Parameter Comparison

Engineering Selection Recommendations

Both the RNF14FTD232R and CMF55232R00FHEB maintain Active product status with full ROHS3 compliance and REACH unaffected designation. The CMF55232R00FHEB provides superior performance margins through increased power dissipation capacity (0.5W vs 0.25W), improved temperature stability (±50ppm/°C vs ±100ppm/°C), and extended maximum operating temperature (175°C vs 155°C). Both components are certified for safety-grade applications with flame retardant construction. Selection between these parts depends on circuit power dissipation requirements and thermal operating conditions rather than electrical compatibility, as resistance and tolerance specifications are identical.

Frequently Asked Questions (FAQ)

Q: Can the CMF55232R00FHEB directly replace the RNF14FTD232R in existing designs?

A: Yes. Both components share identical resistance (232 Ohms), tolerance (±1%), composition (metal film), and axial package configuration. The substitute offers equal or superior performance across all specified parameters.

Q: What is the significance of the different power ratings (0.25W vs 0.5W)?

A: Power rating indicates maximum continuous power dissipation. The CMF55232R00FHEB's higher 0.5W rating provides additional thermal margin in applications with higher current flow. If the original design operates below 0.25W dissipation, both parts perform identically.

Q: Are there physical dimension differences between these parts?

A: Minor dimensional variations exist within axial package tolerances. RNF14FTD232R measures 0.093" diameter × 0.250" length; CMF55232R00FHEB measures 0.090" diameter × 0.240" length. Both fit standard axial component footprints.

Q: How do temperature coefficients affect circuit performance?

A: Temperature coefficient (±100ppm/°C vs ±50ppm/°C) indicates resistance value drift with temperature change. The CMF55232R00FHEB exhibits half the drift rate, providing superior stability in temperature-sensitive applications.

Q: Are both parts suitable for high-temperature applications?

A: The CMF55232R00FHEB supports operation to 175°C versus 155°C for the RNF14FTD232R. Selection depends on maximum ambient or component temperature requirements in the target application.
